Yes, the problem is that I also needed kernel-source-2.4.21 in order to
compile ALSA, and kernel compilation fails when
kernel-patch-2.4.21-powerpc is applied! Now I have my own compiled
kernel-image-2.4.20 with r128 and DRI works.

So, XAA is the only support for 2D acceleration in the XFree86 system?
Or once again I am messing things?

I am trying to evaluate latency for my system, and x11perf kills its 
performance!
